How Incomputable is Finding Nash Equilibria?

Arno Pauly (University of Cambridge, United Kingdom)

Abstract: We investigate the Weihrauch-degree of several solution concepts from noncooperative game theory. While the consideration of Nash equilibria forms the core of our work, also pure and correlated equilibria, as well as various concepts of iterated strategy elimination, are dealt with. As a side result, the Weihrauch-degree of solving systems of linear inequalities is settled.
